System for planning where to place merchandise items and method for planning where to place merchandise items

Abstract

A system for planning where to place merchandise items is configured to create a placement change plan of merchandise; create first virtual work instruction data reflecting a shipment frequency prediction of merchandise on work instruction data relevant to past shipment of merchandise and second virtual work instruction data with placement of merchandise reflecting a placement change plan of merchandise; calculate a predicted value of reduction in shipment working hours from the first and second virtual work instruction data; calculate placement change working hours to perform a placement change plan of merchandise; subtract the placement change working hours from the predicted value of reduction in shipment working hours, thus obtaining a difference; and adopt a placement change plan of merchandise if the difference fulfills a condition of being at or above a certain threshold which is positive or review the placement change plan of merchandise unless fulfilling the condition.

1 . A system for planning where to place merchandise items in a distribution warehouse, the system comprising:
 a merchandise item placement change creation unit which creates a placement change plan of merchandise items based on merchandise item placement data inside the distribution warehouse;   a work plan creation unit which creates first virtual work instruction data reflecting a shipment frequency prediction of the merchandise items on work instruction data relevant to past shipment of merchandise items and second virtual work instruction data with placement of merchandise items reflecting a placement change plan of the merchandise items;   a shipment working hours prediction unit which calculates a predicted value of reduction in shipment working hours based on prediction of the shipment working hours with respect to each of the first virtual work instruction data and the second virtual work instruction data;   a placement change working hours prediction unit which calculates placement change working hours to perform a placement change plan of the merchandise items; and   a control unit which subtracts the placement change working hours from the predicted value of reduction in the shipment working hours, thus obtaining a difference, and determines to adopt a placement change plan of the merchandise items if the difference fulfills a condition of being at or above a certain threshold which is positive or determines to review the placement change plan of the merchandise items unless fulfilling the condition.   
     
     
         2 . The system for planning where to place merchandise items according to  claim 1 ,
 wherein the control unit performs a shipment frequency prediction of the merchandise items based on input of the shipment frequency prediction accepted from a user or past work record data.   
     
     
         3 . The system for planning where to place merchandise items according to  claim 1 ,
 wherein when calculating the placement change working hours based on placement change record data, the placement change working hours prediction unit takes account of weight, size, amount of stock, and moving distance of merchandise items relevant to the placement change plan as variables.   
     
     
         4 . The system for planning where to place merchandise items according to  claim 1 ,
 wherein the control unit outputs one or more placement change plans of the merchandise items and cost-effectiveness graphs obtained from the placement change plans to a user terminal.   
     
     
         5 . The system for planning where to place merchandise items according to  claim 4 ,
 wherein the control unit outputs a ratio of effect, placement change working hours, and time of reduction in shipment work as the cost-effectiveness graphs.   
     
     
         6 . A method for planning where to place merchandise items in a distribution warehouse, the method comprising:
 a first step of creating a placement change plan of merchandise items based on merchandise item placement data inside the distribution warehouse;   a second step of creating first virtual work instruction data reflecting a shipment frequency prediction of the merchandise items on work instruction data relevant to past shipment of merchandise items and second virtual work instruction data with placement of merchandise items reflecting a placement change plan of the merchandise items;   a third step of calculating a predicted value of reduction in shipment working hours based on prediction of the shipment working hours with respect to each of the first virtual work instruction data and the second virtual work instruction data;   a forth step of calculating placement change working hours to perform a placement change plan of the merchandise items; and   a fifth step of subtracting the placement change working hours from the predicted value of reduction in the shipment working hours, thus obtaining a difference, and adopting a placement change plan of the merchandise items if the difference fulfills a condition of being at or above a certain threshold which is positive or reviewing the placement change plan of the merchandise items unless fulfilling the condition and re-executing the first to fourth steps.   
     
     
         7 . The method for planning where to place merchandise items according to  claim 6 ,
 wherein the second step further comprises performing a shipment frequency prediction of the merchandise items based on input of the shipment frequency prediction accepted from a user or past work record data.   
     
     
         8 . The method for planning where to place merchandise items according to  claim 6 ,
 wherein the fourth step further comprising calculating the placement change working hours based on placement change record data, taking account of weight, size, amount of stock, and moving distance of merchandise items relevant to the placement change plan as variables.   
     
     
         9 . The method for planning where to place merchandise items according to  claim 6 , further comprising a sixth step of presenting one or more placement change plans of the merchandise items adopted in the fifth step and cost-effectiveness graphs obtained from the placement change plans to a user. 
     
     
         10 . The method for planning where to place merchandise items according to  claim 9 ,
 wherein the sixth step further comprises presenting a ratio of effect, placement change working hours, and time of reduction in shipment work as the cost-effectiveness graphs.
